45. Sergio Marchionne

CEO

Fiat Chrysler Automobiles NV

The Italian-Canadian Sergio Marchionne is a global automotive player who came to Detroit through Fiat; he was named CEO of Fiat in 2004, became CEO of Chrysler, now FCA, in 2009, and spent five years working to create a merger between the two companies.

He soothed Detroit sensibilities in 2012 when he leased space in Dan Gilbert's Dime Building in downtown Detroit, which Gilbert renamed Chrysler House. Marchionne also headed the local United Way campaign that year.
